SPECIFICATION forming part of Letters Patent No. 655,919, dated August 14, 1960.

' Application and .lpril e, 1899.

States, both residents of New York, in they county of NewYork and State of New York, have invented certain new and useful Improvements in Revolving Fans, of which the following is a specification.

Our invention relates. to that classof re-- volving fans which are held in the hand and revolved by pressure of' the thumb; and it consists in the particular construction, arrangeinent, and operation of the several parts, as hereinafter described, and pointedout in theclaim, reference-being had to the accom panying drawings, in whiche Figure-1 is ajcentral longitudinalsection of the handle and mechanism embodying our invention. Fig. 2 is a face View of the handle and thumb-piece, and Fig. 3a cross-section through the handle;

Like letters of reference indicate like parts throughout the drawings.

A is a tubular handle whichmay be formed of thin sheet metal or any suitable material with an open seam or slot B extending preferably throughout its length and having a portion of the slot widened, as at (3. We prefer to arrange over the ends caps or shells D D, through the latter of which extends a shaft E, to which the fan.F-issecured. The lower end of this shaft is journaled by a hearing in a shell G and by pressure of its end against a suitable hardened plate H, the shell G beingfitted within the tubular handle and securely held in its position by. friction and one or more indentations, as J and the said plate being held in its position between the lower end of the said tubular handle and the cap K, exteriorly fitted over the lower end of the handle. The use of the interiorly-fitted shell serves also to expand the slotted handle outward against the inner walls of the exterior shellat the end and to strengthen this portion of the handle and aids also in securing the said parts in their positions. The

. other journal of the shaft is formed by a perforation in a suitable plate H, arranged at the upper end of the handle in similar manner to the plate H just described.

A worm-gear L is arranged upon the shaft now describe.

serial No- 711,972. (No modeh) fandis arranged and adapted to be actuated by means of movement of the thumb-piece M The construction of these parts we will The thumb-piece is formed flatin the direction of the length of the handle and with bent endsN N, each being provided with grooves O' O, fitted to slide freely along the edges of the widened portion of the slot of the handle. These ends extend sufficiently within the handle and are so disposed with relation to the worm and the pitch of its teeth as to' secure proper mesh therewith and to be adapted to properly actuate it in imparting a reciprocal rotary movement to the shattE of the fan when the thumb-piece M is moved toand'l'ro'by the vertical and ion gitudina-l pressure of thumb of the operator in both directions whileholding the handle in a secure and easy grasp of the hand. It will'be seen that this peculiar mechanism referred to possesses various advantages, particularly inasmuch as the extended ends-0f the said sliding thumb-piece alone serve "to engage the worm and that, further, they are adapted. to be readily adjusted to the pitch of the worm by a slight bending, as may be required;

also, that by forming the grooves 0 O in the ends M M: and in close proximity to their ongaging portions with the worm, as shown, friction of these parts is practically reduced to a minimum. longitudinal movement of the thumb with the handle issecured by this arrangement and that the operator has at all timesdnring the operation substantially the same grasp of the handle and may conveniently at any point rest the thumb and cease operating the fan and without in any way changing the position of the-hand and thumb instantly procced to use the device as an ordinary fan.

Signed at New York, in' the county of New York and State of New York, this 1st day of April, A. D. 1899.
